I agree with the points being raised, though I must admit I'm a bit hesitant to speak up, as I worry it might be misunderstood or lead to issues on the forum to get me banned.
It's not just about selling - I've noticed some individuals offering services like editing others' work or customizing panels for a fee. I brought this up previously and received a warning from that user in open, which made me reluctant to say more.
Unfortunately, I feel that raising these concerns might once again put me in someone’s crosshairs. For example, simple tasks like changing a bar graph to a line graph are sometimes charged at $5 or more, and that too for other's work/panels especially targeting newcomers like myself who are still learning, novice and old aged.
We are the soft targets for these people!
